ACETYLENE-GAS GEN ERATOR.'

SPECIFICATION forming part of Letters Patent No. 635,599, dated October24, 1899.

Application filed February 25, 1899. Serial No. 706,874. (No model.)

T cull whom t may concer/1,:

Be it known that I, ISAAC O. RUSSELL, of Indianapolis, county of Marion,and State of Indiana, have invented a certain new and usefulAcetylene-Gas Apparatus; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, in which like letters refer to like parts.

My invention relates to a novel arrangement and construction of anacetylene-gas lamp or apparatus, as will hereinafter appear.

One feature consists in passing the gas after its generation through awater-tank by means of a coiled tube or otherwise to the outlet orburner, combined with an automatically-adjustable gas-chamber forholding the gas before it passes through the coiled tube,

whereby the capacity of the gas-chamber will I pear from theaccompanying drawings and the description and claim following.

In the drawings, Figure 1 is a central vertical section of anacetylene-gas lamp embodying my invention. Fig. 2 is a bottom View ofthe Water-tank, being partly broken away at one side.

In detail 1 is a cylinder-casin g closed at the bottom and open at thetop. At its upper end it is provided with internal threads 2. Itcontains a depressible cup-shaped casing 4, with the bottom 5 thereofsupported upon the spiral spring G, that in turn rests upon the bottomof the casing l. The inner casing fits air-tight within the casing 1,and the length vertically of the inner casing 4 is enough less than thelength of the casin g 1 to permit the insertion of the spring 6 and thevertical play and movement of the inner casing 4 for the purposeshereinafter mentioned. The inner casing4 contains carbid 3, surroundinga centrally upwardly extending tube 7, that is perforated in the lowerhalf thereof. The lumps of carbid are held in close contact with eachother by a loose depressible ring or plate 8, that is perforated for theescape of the gas. It is depressed by the spiral spring 9.

The space above the plate or ring 8 forms 55 a gas-chamber, where thegas collects after its generation and escape through said plate. Abovethe gas-chamber I secure the waterchamber, which consists of ,thecylindrical casing 10, provided at its lower end with ex- 6o ternalthreads to engage theinternal threads 2 at the upper end ofthe lowercasing 1,where by the two casings are secured together. The joint shouldbe air-tight. The casing 10 has a bottom 1l and a top 12. Water issupplied 65 through a threaded opening in the top closed by thescrew-cap 13. The bottom has an opening at 14 for the escape of thewater from said chamber into the pipe 15, that is rigidly secured tosaid bottom and so arranged as to 7o extend centrally downward therefromwithin the tube 7 almost to the bottom 5 of the gasgenerating chamber.The lower portion of the tube 15 is perforated. The water passes throughsaid tube into the tube 7 and from 75 it through its perforations intothe chamber\` Y containing the carbid. A valve 16 for closing theopening 14 from the water-chamber consists of a pin or rod withathreaded head 17 at its upper end, which extends through a 8o threadedopening in the top of the Waterchamber. The gas that collects in thechamber above the ring or plate 8 passes through a perforated shield 1Sand through the opening 19 in the bottom 11 of the water-chamber 8 5into the coiled tube 20, that is coiled against the casing 10, andissues at its upper end through the opening 21 into the outlet-tube 22,that leads to the burner. In the form of lamp which I have used andadopted for 9o house-illuminating purposes the casing is aboutthree-inches in diameter and the tube 20, coiled within the upper casing10, is about twelve feet long.

Since the water-chamber contains water through which the coiled tube 20extends from bottom to top, it is obvious that the gas would becomecooled before it reaches the burner, and also that its particles whilepassing through said long tube will be thoroughly Ioo mixed andcommingled, and, furthermore, the pressure or movement of the gas whilepassing through so long a tube will become regulated and uniform, sothat it will pass to the burner under a uniform pressure. The uniformityof pressure and movement of the gas is also partially caused by theautomatically-distensible gaschamber above the ring or plate 8. It` isobvious that when the gas in said chamber attains a high pressure itwill press said plate, the casing 4, and the bottom 5 downward as far asthe tension of the spring will permit. When the movement of gas in saidchamber diminishes and as it diminishes, the spring 6 will force thecasin g 4 and the carbid upward, thus diminishing the capacity of thegas-chamber. In-this Way the pressure of the gas in said chamber will bemuch more uniform than if such arrangement were not employed. It willpass into the coiled tube 2O under. suchpressure, and greateruniformitywill be established before it escapes from said tube for the reasonbefore mentioned. The spring 9, with itsuppcrend resting against thebottom ll ofv the Water-chamberand its lower end resting upon the plate`or ring S, will keep said platev or ring down in position. By thisconstruction, therefore, it is seen that 4I have a very compactconveniently arranged lamp adapted for house, headlight, or otherpurposes. I have the Water-tank between the gas-chamber and thegas-generating chamber, which are usually hot While gas is beinggenerated, and the burner or blaze. It also cools the gas before itreaches the burner and feeds the same to the burner at a uniform rate,so as to maintain a bright llame of uniform size.

In order to keep the generating-chamber cool, I provide about it awater-jacket 21. This is shrunk on and is conical in form, the lower endbeing widened to form a broad base for the lamp.

What I claim as my invention, and desire to secure by Letters Patent,is-

An acetylene-gas lamp including a casing a carbid-receptacle supportedby a spring airtight within the casing, a plate loosely placed on thecarbid, a spring acting on said plate ISAAC O. RUSSELL. lVitnesses:
